It is widely used in various fields, such as physics, chemistry, materials science, electronics, and medical equipment. The production of a vacuum chamber is a highly precise and complex process, mainly including design, material preparation, manufacturing, welding, assembly, and testing. The main body of the vacuum chamber needs to be welded, and then doors, windows, flanges, etc., are assembled onto the vacuum chamber. After assembly, a series of tests are performed, including helium leak detection, pressure testing, and vacuum level testing, to ensure that it meets design requirements.

[0003] In the existing production process of vacuum chambers, the movement between each stage from welding and assembly to testing is a critical link.

[0010] Preferably, the transmission wheels are symmetrically located on opposite sides of the support base, and a ball bearing structure that contacts and engages with the support plate is embedded in the bottom of the support base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The welding, assembly, and testing production line for the vacuum chamber uses the main positioning track to limit the movement of the limiting plate, and the vacuum chamber positioning seat and support base are positioned and stabilized by the limiting plate, ensuring the stability of the conveying.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a production line for welding, assembling, and testing vacuum chambers, including a main production line 1. The main production line 1 has a feeding station 6, a welding station 4, an assembly station 3, a testing station 5, and an unloading station 7. The main production line 1 also has a main positioning track 2 forming a ring structure. A secondary positioning track 201 extending to the welding station 4 and the assembly station 3 is integrally provided on the side of the main positioning track 2. The lower ends of the main positioning track 2 and the secondary positioning track 201 are connected to a support plate 14. The main positioning track 2 and the secondary positioning track 201 have the same structure, and the upper end of the main positioning track 2 is bent inwards. A groove is formed on the inner side of the upper end of the main positioning track 2. This structure, by setting the ring-shaped main positioning track 2, allows for… The vacuum chamber positioning seat 8 moves and is conveyed along the production line, facilitating loading and unloading. The main body 1 of the production line also features the vacuum chamber positioning seat 8, with a dual-head drive motor 12 installed below it. A limiting plate 10, which penetrates and engages with the dual-head drive motor 12, is located below the vacuum chamber positioning seat 8. The groove of the main positioning track 2 is movably engaged with the limiting plate 10, and the grooves of the main positioning track 2 and the auxiliary positioning track 201 are interconnected. This structure uses the groove of the main positioning track 2 to limit the movement of the limiting plate 10, ensuring reliable movement of the vacuum chamber positioning seat 8. The vacuum chamber positioning seat 8 is located above the main positioning track 2 and the auxiliary positioning track 201, and the rotating positioning disk 9 is rotatably engaged with the vacuum chamber positioning seat. Inside seat 8, this structure allows the vacuum chamber positioning seat 8 to move above the main positioning track 2 and the secondary positioning track 201. Simultaneously, the rotating positioning disk 9 can rotate relative to the vacuum chamber positioning seat 8. The vacuum chamber positioning seat 8, restricted by the limit plate 10, can only move linearly. The dual-head drive motor 12 is an existing mechanism that uses two independent motor structures for rotational drive, ensuring the different degrees of rotation required by the rotating positioning disk 9 and the support base 13. The upper and lower output shafts of the dual-head drive motor 12 are respectively connected to the rotating positioning disk 9 and the support base 13 via couplings. Transmission wheels 11 are installed on both sides of the support base 13. The limit plate 10 is a horizontally arranged rectangular plate structure, and the limit plate 10 and the dual-head drive motor 12... The outer shell of component 2 is welded and fixed. This structure allows the dual-head drive motor 12 to be reliably positioned via the limiting plate 10, and enables the dual-head drive motor 12 to drive the rotating positioning disk 9 and the support base 13 to rotate respectively. When the support base 13 rotates, the conveying orientation can be adjusted. When the rotating positioning disk 9 rotates, the welding, assembly, and inspection orientation can be adjusted. The limiting plate 10, designed as a rectangular structure, allows it to move between the main positioning rail 2 and the secondary positioning rail 201, ensuring that the vacuum chamber positioning seat 8 can move along the orientations of the loading station 6, welding station 4, assembly station 3, inspection station 5, and unloading station 7. Multiple sets of welding stations 4, assembly stations 3, and inspection stations 5 can be set as needed.The loading station 6 and unloading station 7 are located in the same area. The drive wheels 11 are symmetrically positioned on opposite sides of the support base 13. The bottom of the support base 13 has a ball bearing structure embedded in it, which contacts and engages with the support plate 14. This structure allows the mechanism driven by the drive wheels 11 to be installed within the support base 13. After rotational adjustment, the drive position of the drive wheels 11 can be adjusted, allowing the support base 13 to move along the track as needed. The support plate 14 provides reliable bottom support for the support base 13. The stable movement of the vacuum chamber positioning seat 8 ensures stable transport of the vacuum chamber on the main body 1 of the production line, effectively avoiding subsequent position adjustments and improving work efficiency.

[0018] Working Principle: When using this vacuum chamber in the welding, assembly, and testing production line, the vacuum chamber is first welded, assembled, and tested on the main body 1 of the production line. The base of the vacuum chamber is fixed to the rotating positioning plate 9 at the loading station 6 for stability. The transmission wheel 11 rotates under the drive of the motor, driving the support base 13 to move. The support plate 14 is used for bottom support of the transmission wheel 11. The limiting plate 10 is used for limiting the movement under the snap-fit ​​positioning of the main positioning track 2 to ensure reliable movement of the vacuum chamber positioning seat 8. When the vacuum chamber positioning seat 8 moves to the turning point, the double-head drive motor 12 can drive the support base 13 to rotate 90° to achieve turning. When the vacuum chamber positioning seat 8 moves to the secondary positioning track 201, the support base 13 turns again, so that the vacuum chamber positioning seat 8 can move to the welding station 4 and the assembly station 3. The vacuum chamber after welding and assembly is moved to the testing station 5 for testing through the vacuum chamber positioning seat 8. Finally, it moves to the unloading station 7 for unloading, thus completing a series of operations.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
